LAMP.

SPECIFICATION forming part of Letters Patent No. 484,323, dated October 11, 1892. Application filed August 12, 1891. Serial No. 402,423. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN KIRBY, J r., a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Lamps; and I do hereby declare that the following is a full, clear, and exact description of the invention.

My invention relates to oil-lamps adapted to be suspended from the ceilings of railroadcars, steamboats, and other similar supports, and has special reference to that class of lamps in which a central chimney is employed, around the exterior of which the wicks are arranged, the flame first taking a downward course, and thence upward through the center of the chimney in substantially the same manner as in the well-known Siemens regenerative gas-lamp.

The invention consists, chiefly, in the manner of arranging the reservoirs and wicktubes whereby they may be readily detached from their support, together with certain other improved features of such lamps, as will be hereinafter fully described with reference to the accompanying drawings, .in which Figure 1 is a side view of the lamp, onehalf being shown in vertical section through its center, a hand being represented in the act of removing one of the reservoirs from its holder. Fig. 2 is an enlarged broken perspective view showing the lower part of the lamp detached from the lamp-hanger. Fig. 3 is a broken perspective view of the lamphanger, showing the chimney in a raised position and the means employed for raising the same. Fig. 4. represents the wick-tube cap detached from the tubes. Fig. 5 is a broken perspective view of a single annular detachable reservoir adapted to be coupled to the lamp-hanger in lieu of the two shown in 1. Fig. 6 represents a broken perspective View of the air-deflecting and bezel rings in a lowered position and shows the manner in which they are hinged to the coupling-ring. Fig. 7 is a section showing the manner in which the bezel-ring and air-deflector are secured to the coupling-ring.

Like letters of reference indicate corresponding parts in all the figures.

' A represents a hollow centrally-contracted hanger or frame, having its upper end some what enlarged for rigid support to a car-ceiling or other place from which it is to be suspended, and to the lower end of which reservoirs are coupled, as will presently appear. This hanger is provided with perforations B B near its lower end, which admit air to the burner, the latter perforations corresponding.

with openings in a coupling-ring hereinafter described, and the upper end of the hanger is provided with perforations O, the said perforations being made of proper size and numher to counterbalance the currents of air within the hanger and thus protect the flame from irregular air currents which may at times surround the lamp, for if the flame is not protected in some such manner as above described these irregular air-currents will disturb it and cause it to smoke and in some instances to be extinguished.

The lower end of hanger A is provided with an annular perforated ring D, having studs or located on its periphery. A number of guidearms 1) project from the interior of hanger A toward the center, whose function will presently appear.

E represents a tube suspended from the overhead support F of the lamp and extending to about midway of the hanger A. The lower end of this tube is turned inward, as seen in Fig. 1, at 0, its upper end being provided with perforations or openings d to allow free circulation of air through an exterior ventilator H, through which latter the products of combustion escape to the open air, as indicated by arrows in Fig. 1.

G is the lamp-chimney, which is of less diameter than tube E and flanged outwardly at its upper end to fit snugly within the tube E. A collar 6, Fig. 1, is attached to and encircles chimney G and supports the same by resting on flange c of tube E.

I is a cylinder-shaped piece of metal or other suitable material of less diameter than chimney G, to which it is attached, as seen in Figs. 1 and 2. To the interior of this cylinder at its lower end is attached by any suitable means another cylinder J, preferably made of porcelain or other similar refractory material and flanged outward at the bottom, an annular ring a, having a central opening of proper diameter to regulate the draft, being located just above the cylinder J, chimney G being perforated to allow air to pass between it and cylinder I in the direction indicated by arrows in Fig. 1.

K represents a wind-break or hurricane-cap attached to and located above the top of chim ney G to prevent downward currents of air entering the latter.

When lighting the lamp, it is desirable to first raise chimney G sufficient to immediately form an upward draft through the center of the chimney, and thereby prevent the accumulation of soot around the exterior of the latter, and for this purpose a projecting arm or handle f is attached to the chimney and extends through a bayonet-slot gin tube E, and also through a corresponding slot in hanger A, as more clearly shown in Fig. 3. When it is desired to raise the chimney,han- (110 f is lifted and turned into the horizontal portion of slot g, and as the handle f carries with it the chimney G the latter will remain elevated until the former is turned. back into the vertical portion of slot g, when both will return to their normal positions, the guidearms 1) serving to retain the lower endiof the chimney in a central and proper position with relation to the other parts of the lamp.

L represents oil-reservoirs of the ordinary student-lamp type provided with the usual valves h and two or more studs Two such reservoirs are shown held in receivers M,the. latter being provided With bayonetslots. j, with which studs/i engage to hold the reservoirs in place in the manner shown in Fig. 1. The receivers M also act asv oil-holders and are attached to. an annular ring N, provided with air-openings (1 which ring fits ever ring D. of the lamp-hanger previously described, and is also provided with bayonet-slots k to engage studs a of ring D. By thus engaging studs 0, with the horizontal portions of slots 7:, ring N, with the receivers and'other parts attached, is coupled to. the lamprhanger, as. seen in Fig. 1. A suitable lock or catch may be employed to prevent uncouplingof the parts last described by any agitation: to which the lamp may be subjected. 1

A deflecting-ring 0, provided with'air-openlugs Z, and a bezel-ring P, carrying a glass bowl Q, forming the bottom of the lamp, are each hinged at a a to the ring N and held up to place by a spring-catch m, located opposite'the hinge, as more clearly shown in. Figs. 6 and 7. By releasing the spring-catch m deflecting-ring 0 and bezelring P, together with bowl Q, will drop to the positions shown in Fig. 6, thus allowing free access to the burner and wicks for trimming, he.

Wick-tubes R are attached to the receivers M and radiate therefrom, passing through ringN toward the center of the lamp, forming at their inner ends a circular burner X, with an annular opening for the burning ends 0. of the wicks, which meet each other here and when burning give out a circular flaniea,

first descending around the exterior of the chimney and then ascending through its center, as seen in Fig. 1.

A shield or cap S, Fig. 4, one end of which is perforated, forming a series of bars n, is placed over the annular open end of the Wicktube and secured in place by any suitable fastening, its function being to form a stop for the burning ends of wicks 19, thereby insuring a uniform flame at the maximum point, the ends of the wicks coming in contact with the bars n, which prevent their further adjustment.

As the oil commonly used for the lighting of railroad-cars, steamboats, 820., is of aheavy grade, burners for such oil must be constructed with special reference to. its use, and it. is essential that the point of combustion be as close to the oil as other requirements will permit. Itisalso desirablethat the oil should be maintained at a constant level until the reservoir from which it is supplied is. exhausted, as in such construction the capillary attraction of the wicks will, be uniform during the consumption of oil from, the reservoir, and therefore asufficient supply of oilwill be maintained at the burning points of wicks 19 until the reservoiris empty. For the reasons above stated I prefer the construction of reservoirs shown in; Fig. 1. As an aid in supplying the flame with oil, I employ auxiliary wicks g, which dip. into the oil and extend partially through the wick-tubes toward the point of combusltion the wick-tubes being deepened to receive them, as shown in section in Fig. 1. To advance and retract the wicks p, Ie1n-ploy a number of spur-wheelsv, mounted on a shafts, behind which an opening (not shown). is made in the topside of the wick-tubes for convenience in inserting the wicks. In the bottom of the reservoirs I arrange a cylinder or guard t, preferably perforated, as seen in section in- Fig. 1, around about which the wicks lie in the bottom of the oil-holder. serves to, keep, the wicks clear of the stem U of valve 7.2 which stem when the reservoir is secured in place, as seen, in section in Fig. l, rests upon the bottomof the oil-holder, thereby raising the valve and permitting oil to flow from the reservoir until it rises to the lower end of a tube 1;, when the air is there- This cylinder 1 IIO by prevented from entering the reservoir and I the flow of oil ceases, continuing thereafter in small quantitiesonly as the oil in the holder is consumed and, air thusadmitted to the res ervoir, by which operation the oil maintains a constant level within the holder while feeding from the reservoirs and being consumed.

In Fig. 5. I have shown. a single annular oil holder or reservoir'l, carried by a couplingring U, adapted to couple to the hanger-ring D and to be substituted for the reservoirs previously described, and. shown in Figsl and 2. This form of reservoir is, however, some.- what objectionable for the reasons, that itcasts aheavy shadow overhead, and as the oilis consumed it recedes from the burning point of? the wicks, which, in consequence thereof, become crusted, thereby requiring frequent attention and trimming, and for the further reason that to remove the reservoir for filling the glass bowl must be removed with it, and the latter is liable to get broken in handling, while the reservoirs shown in Fig. 1 can be removed and filled independently without uncoupling the other parts, which need only be done when new wicks are required, and, owing to the oil remaining at one level, renewing of the wicks is seldom required.
